METHOD OF PRESSURE-PUMPING READY-MIXED CONCRETE
A method of pressure-pumping a ready-mixed concrete includes pouring a preceding material for pumping into a piping, then, pouring the ready-mixed concrete into the piping, and pressure-pumping the preceding material and the ready-mixed concrete, so that a lubricant layer formed of the preceding material is formed on an inner surface of the piping to thereby pressure-pump the ready-mixed concrete inside the lubricant layer made of the preceding material. The preceding material includes calcium carbonate as a main material, to which cellulose nanofibers and erythorobic acid are added, and an amount of the cellulose nanofibers is 0.005 wt % or more.
